Love this build Steve, especially the seat but you must have a small ****. That sprung section looks small, even with all the foam on top?
I thought you might feel the edges of the hole if it is too small?
Looks good but what is its function?
Doesn't the transverse spring locate the axle laterally anyway?
Ah! I was guessing that the other end was fixed. Looks great BTW.
Spiral bevel gears can be designed to run with an offset between the input and output shaft axis. In this case the centreline of the prop is below the centreline of the axle. The prop to diff drive is a spiral bevel rather than a straight cut bevel(which would need align axes).Why does the propshaft go on below the centre of the diff, is there some gearing involved?
Locates the axle sideways
Ok but far too technical for me
It's not technical at all mate, it's what is correct for the job, what would you of used then ???
I didn't read it as "it's too technical for the job", simply that Parm didn't understand the technical function of the piece
A transverse leaf spring should have swinging shackles both ends (or slip plates) because it gets longer as it's compressed. If you fix either end to locate the axle, it'll crab the axle off to the side if you load it or hit a bump. More than that though, it'll be like the automotive equivalent of balancing a broom on your finger.
With longitudinal leaf springs you can use them to locate the axle transversely and longitudinally because a few inches variability in wheelbase is neither here nor there (ok, so you do get bump steer if one side is compressed more than the other, but unless the twist is extreme it's not usually a concern). On a driven axle like this, you have an extendable propshaft (splined slip joint in either end or slapped in the middle).
Designed absolutely right, you shouldn't need any sliding sections in the prop with a transverse leaf and appropriately positioned locating members - absolutely right is difficult in reality though, so a small amount of length flexibility is 'normal'...
If your longitudinal link rod pivots are exactly aligned with your prop UJs a slip joint becomes superfluous as the arcs are identical.
Until you get a bump on one side and not the other of course.
